Description

A virus has taken over the landscape and has begun converting everyone into one of seven different strains of virus. It is up to the player to take them on, using only rocks. This is to be taken literally: the player only controls a cursor which is used to pick up rocks and throw them at the blobs which are floating around. Every killed blob results in an increased score.

As well as the single player campaign, there is also a challenge mode available with four different difficulty levels (Easy, Intermediate, Hard and Insane) that offer an array of different challenges including 'High Score Challenges', 'No Aiming', 'Purple Invasion' and 'Mind Games'. 7strains also offers cooperative gameplay for up to four persons in offline play.
